Maintains your MacBook battery health

BatteryBox powers your laptop rather than charging it, keeping the battery at the same charge percentage.

By bypassing the MacBooks built-in battery, BatteryBox minimizes the number of cycles (and stress) on the internal battery, prolonging it's life.

Charging your laptop cycles the built-in battery, degrading it over time and leading to eventual failure. Some energy is also lost and never gets to your laptop as it flows through this more inefficient path.

3x longer life than any other battery

The batteries in BatteryBox keep working like brand new even after many years, thanks to patent-pending BatteryOS artificial intelligence. This technology provides better performance without battery-life degradation.
